琵琶湖周辺の気象 (2) -琵琶湖北部の湖陸風-

Abstract

In order to study the land and lake breeze in the northern part of the Lake Biwa basin, ananalysis of the surface wind at Hikone Local Observatory in July and August, 1977 and an ob-servation of the vertical wind distribution were carried out at Onoe, Funaki and Hikone aroundthe Lake Biwa from 9 to 10 Augnst, 1978.The land and lake breeze appears in half the number of days during the period and the lakebreeze changes its direction clockwise at Hikone Local Observatory. When the lake breeze pre-vails, the atmosphere over the Lake Biwa can be divided vertically into three layers; the loweris the divergent layer with the lake breeze, the middle is the convergent layer with the anti-lakebreeze and the upper is the layer with the general wind.
